Definitions
- the invention relates to a housing arrangement with at least one overheating-prone electrical unit, a method for protecting at least one environment of at least one housing arrangement and a rail vehicle with at least one housing arrangement.
- At least one battery can supply energy to electrical devices in at least one rail vehicle car.
- the battery can be arranged freely in a battery box. However, this arrangement no longer meets the current requirements for fire protection. It is also known that the battery can be arranged in an open battery tray, which in turn is arranged in a battery box. The battery box must comply with ventilation and fire protection standards.
- the publication WO 01/20961 A1 describes a control cabinet with a locking mechanism comprising two abutting perforated plates and a spring mechanism. The perforations of the two plates are superimposed, so that an air exchange is possible. When the temperature at the shutter mechanism exceeds a predetermined temperature, the plates are displaced relative to each other so that perforations of a first plate abut non-perforated portions of a second plate. This prevents flames from escaping from the control cabinet.
- the disadvantage here is that with closed closure mechanism also a passage of gases is prevented. In addition, the shutter mechanism is prone to failure.
- the publication EP 2 910 284 A2 concerns an explosion protection valve for ventilated shelters.
- the explosion protection valve comprises two U-shaped bent and perforated covers and a spring. In a pressure wave, an outer cover is pressed against an inner cover so that perforations of the outer cover adjoin non-perforated portions of the second cover. As a result, the explosion protection valve is closed and forms a flame guard.
- the disadvantage here is that the explosion protection valve reacts only in an explosion and remains in a rest position with an explosion-free flame formation.
- the publication US 3,955,949 discloses a filter device for a kitchen extractor system wherein the haze is grease particles or the like. contains.
- the filter device retains flames and is permeable to heat and vapor.
- Elongated baffles with angled edges are arranged parallel and offset from each other.
- a disadvantage is that a spatially open flame formation takes place, whereby only the extractor system is protected.
- the invention is therefore based on the object to provide a housing assembly that meets both ventilation and fire safety requirements and is reliable.
- the object is achieved in a housing arrangement having at least one overheating-prone electrical unit, wherein the housing arrangement comprises at least one receiving device, in which the electrical unit is accommodated, and at least one covering device and wherein the covering device covers the receiving device on at least one associated open side and at least one first cover plate and at least one second cover plate, wherein the first cover plate is arranged parallel to the second cover plate and the first cover plate having first openings and the second cover plate second openings.
- the first cover plate and the second cover plate are spaced from each other and the first openings in the first cover plate are arranged offset from the second openings of the second cover plate independently of a thermal state of the electrical unit.
- An advantage of the housing arrangement according to the invention is that requirements for ventilation and fire protection are equally met. Fire protection is required, since a fire or a flame-forming or flaming-free overheating can occur on electrical units.
- the electrical unit can be, for example, a battery unit, in particular a battery unit of a rail vehicle. Other types of overheating-prone, ie flammable, combustible, fire-endangered and / or flammable electrical units or flame-free, smoke-generating electrical units are also conceivable.
- the housing arrangement forms a fire protection cover and compensates for a fire risk that emanates from the electrical unit, ie the fire does not break out of the housing. Fire flames remain inside the enclosure.
- Ventilation is required to dissipate heat, fumes and / or gases generated during a battery unit charging process.
- a limited installation space e.g. in a rail vehicle, eliminates a separate outer box for the battery unit, whose function is taken over by the housing assembly.
- the receiving device may have a shape of a trough.
- Another advantage is that the structure of the housing assembly is simple and requires little manufacturing effort. In addition, the construction is reliable, because it can be dispensed with a failure-prone adjustment.
- a gap between the first cover plate and the second cover plate is present and preferably has a gap width between 8 mm and 12 mm including a tolerance range, the gap width in particular 10 mm including a tolerance range is.
- a minimum clearance is required.
- a gap width between 8 mm and 12 mm including a tolerance range, in particular 10 mm including a tolerance range is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
- a total area of the first openings and the second openings together is between 200 cm 2 and 230 cm 2 including a tolerance range.
- the limitation of the total area is required because of the requirements for ventilation and fire protection.
- the total area between 200 cm 2 and 230 cm 2 is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
- first openings and / or the second openings may each have the same or different diameters. This allows eg in areas an increased fire hazard at the electrical unit smaller diameter can be chosen than in less vulnerable areas.
- the first openings and the second openings each have a diameter which is less than 25 mm, the diameter being in particular 20 mm including a tolerance range.
- Such selected diameter are particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
- offset distances in a longitudinal direction and / or a transverse direction are present between the first openings and the second openings. Thereby, a direction of a gas outflow can be influenced.
- the offset distances between the first openings and the second openings can each be the same size or different sizes. Equal ventilation distances are guaranteed for equal offset distances. For differently sized offset distances, e.g. In more fire-prone areas on the electrical unit be provided a greater offset distance than in less fire-prone areas.
- the offset distances between the first openings and the second openings are each greater than 25 mm.
- a test criterion for the ventilation and the fire protection in a battery unit of a rail vehicle is met, i. E. a gap gauge with an outer diameter of 25 mm fits neither vertically nor obliquely through the offset to each other first openings and second openings.
- the gap gauge is a cylindrical steel rod that complies with fire safety standards and serves to verify compliance with the standards.
- each edge distance is greater than a respective predetermined minimum distance.
- the first cover plate and the second cover plate may each comprise a material with a predetermined fire resistance, in particular with a fire resistance of 10 minutes, the material comprising in particular steel.
- the specified fire resistance results from the fire protection requirements.
- a fire resistance of 10 minutes is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
- Steel generally provides good fire resistance.
- a first thickness of the first cover plate and a second thickness of the second cover plate are each at least 1 mm including a tolerance range.
- Such a dimensioned first thickness or second thickness is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
- the electrical unit is a battery unit and / or the first cover plate and the second cover plate are fastened to one another, in particular by means of rivet connections, and / or the cover device is fastened to the receptacle, in particular by means of screw connections.
- Such a structure allows easy assembly and disassembly. If the receiving device is provided for a battery unit of a rail vehicle, this structure is particularly advantageous.
- the solution of the problem in a method for protecting at least one environment of at least one housing assembly In a flame development on the electrical unit, the first cover plate and the second cover plate together form a gas-permeable flame arrester, the first cover plate and the second cover plate occupy the same gas-permeable position with a flame development on the electrical unit as in a flame-free operation of the electrical unit.
- a gas permeability is thus ensured both with a flame formation and with a flame-free operation.
- the method according to the invention thus advantageously meets the requirements for ventilation and fire protection. As a result, safe operation is possible, because it can be dispensed with a failure-prone adjustment mechanism.
- gas evolution on the electrical unit may cause gas flow through the second openings, the gap between the second cover plate and the first cover plate, and through the first openings.
- the ventilation requirements are met, whereby the gas flow can flow through a simply constructed flow path.

Diese Aufgabe wird erfindungsgemäß mit einer Gehäuseanordnung mit mindestens einer überhitzungsgefährdeten elektrischen Einheit nach Anspruch 1 gelöst. Weiterhin wird die Aufgabe mit einem Verfahren zum Schützen mindestens einer Umgebung mindestens einer Gehäuseanordnung nach Anspruch 13 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.This object is achieved with a housing arrangement with at least one overheating endangered electrical unit according to claim 1.

Advantageous embodiments of the invention are contained in the subclaims.
Erfindungsgemäß besteht die Lösung der Aufgabe in einer Gehäuseanordnung mit mindestens einer überhitzungsgefährdeten elektrischen Einheit, wobei die Gehäuseanordnung mindestens eine Aufnahmevorrichtung, in der die elektrische Einheit aufgenommen ist, und mindestens eine Abdeckungsvorrichtung umfasst und wobei die Abdeckungsvorrichtung die Aufnahmevorrichtung an mindestens einer zugehörigen offenen Seite abdeckt und mindestens eine erste Deckplatte und mindestens eine zweite Deckplatte umfasst, wobei die erste Deckplatte parallel zu der zweiten Deckplatte angeordnet ist und die erste Deckplatte erste Öffnungen und die zweite Deckplatte zweite Öffnungen aufweisen. Die erste Deckplatte und die zweite Deckplatte sind voneinander beabstandet und die ersten Öffnungen in der ersten Deckplatte sind unabhängig von einem thermischen Zustand der elektrischen Einheit jeweils versetzt zu den zweiten Öffnungen der zweiten Deckplatte angeordnet.According to the invention, the object is achieved in a housing arrangement having at least one overheating-prone electrical unit, wherein the housing arrangement comprises at least one receiving device, in which the electrical unit is accommodated, and at least one covering device and wherein the covering device covers the receiving device on at least one associated open side and at least one first cover plate and at least one second cover plate, wherein the first cover plate is arranged parallel to the second cover plate and the first cover plate having first openings and the second cover plate second openings. The first cover plate and the second cover plate are spaced from each other and the first openings in the first cover plate are arranged offset from the second openings of the second cover plate independently of a thermal state of the electrical unit.
Ein Vorteil der erfindungsgemäßen Gehäuseanordnung besteht darin, dass Anforderungen an eine Belüftung und einen Brandschutz gleichermaßen erfüllt werden. Der Brandschutz ist erforderlich, da an elektrischen Einheiten ein Brand bzw. eine flammenbildende oder flammenbildungsfreie Überhitzung entstehen kann. Die elektrische Einheit kann z.B. eine Batterieeinheit, insbesondere eine Batterieeinheit eines Schienenfahrzeugs sein. Andersartige überhitzungsgefährdete, d.h. entflammbare, brennbare, brandgefährdete und/oder entzündliche elektrische Einheiten oder flammenbildungsfreie, rauchbildende elektrische Einheiten sind ebenfalls denkbar. Die Gehäuseanordnung bildet einen Feuerschutzabschluss und kompensiert ein Brandrisiko, das von der elektrischen Einheit ausgeht, d.h. der Brand bricht nicht aus dem Gehäuse aus. Bei einem Brand entstehende Flammen bleiben innerhalb der Gehäuseanordnung.An advantage of the housing arrangement according to the invention is that requirements for ventilation and fire protection are equally met. Fire protection is required, since a fire or a flame-forming or flaming-free overheating can occur on electrical units. The electrical unit can be, for example, a battery unit, in particular a battery unit of a rail vehicle. Other types of overheating-prone, ie flammable, combustible, fire-endangered and / or flammable electrical units or flame-free, smoke-generating electrical units are also conceivable. The housing arrangement forms a fire protection cover and compensates for a fire risk that emanates from the electrical unit, ie the fire does not break out of the housing. Fire flames remain inside the enclosure.
Eine Belüftung ist erforderlich, damit Wärme, Rauchgase und/oder bei einem Ladevorgang einer Batterieeinheit entstehende Gase abgeführt werden können. Bei einem begrenzten Einbauraum, z.B. bei einem Schienenfahrzeug, entfällt ein separater äußerer Kasten für die Batterieeinheit, dessen Funktion von der Gehäuseanordnung übernommen wird. Die Aufnahmevorrichtung kann eine Form eines Trogs aufweisen. Ein weiterer Vorteil liegt darin, dass der Aufbau der Gehäuseanordnung einfach ist und einen geringen Fertigungsaufwand erfordert. Außerdem ist der Aufbau zuverlässig, denn es kann auf einen störungsanfälligen Verstellmechanismus verzichtet werden.Ventilation is required to dissipate heat, fumes and / or gases generated during a battery unit charging process. With a limited installation space, e.g. in a rail vehicle, eliminates a separate outer box for the battery unit, whose function is taken over by the housing assembly. The receiving device may have a shape of a trough. Another advantage is that the structure of the housing assembly is simple and requires little manufacturing effort. In addition, the construction is reliable, because it can be dispensed with a failure-prone adjustment.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist unabhängig von einem Zustand der elektrischen Einheit ein Spalt zwischen der ersten Deckplatte und der zweiten Deckplatte vorhanden und weist vorzugsweise eine Spaltbreite zwischen 8 mm und 12 mm einschließlich eines Toleranzbereichs auf, wobei die Spaltbreite insbesondere 10 mm einschließlich eines Toleranzbereichs beträgt. Zur Gewährleistung einer ausreichenden Belüftung ist ein Minimalabstand erforderlich. Aus Gründen des Brandschutzes ist außerdem ein Maximalabstand einzuhalten, denn mit einem zunehmenden Abstand nimmt eine brandschutztechnische Wirkung ab. Eine Spaltbreite zwischen 8 mm und 12 mm einschließlich eines Toleranzbereichs, insbesondere 10 mm einschließlich eines Toleranzbereichs, ist besonders vorteilhaft, wenn die elektrische Einheit eine Batterieeinheit eines Schienenfahrzeugs ist.According to an advantageous embodiment of the invention, regardless of a state of the electrical unit, a gap between the first cover plate and the second cover plate is present and preferably has a gap width between 8 mm and 12 mm including a tolerance range, the gap width in particular 10 mm including a tolerance range is. To ensure adequate ventilation, a minimum clearance is required. For reasons of fire protection also a maximum distance is to be observed, because with an increasing distance decreases a fire protection effect. A gap width between 8 mm and 12 mm including a tolerance range, in particular 10 mm including a tolerance range, is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
In einer bevorzugten Weiterbildung der Erfindung beträgt eine Gesamtfläche der ersten Öffnungen und der zweiten Öffnungen zusammen zwischen 200 cm2 und 230 cm2 einschließlich eines Toleranzbereichs. Die Begrenzung der Gesamtfläche ist wegen der Anforderungen an die Belüftung und den Brandschutz erforderlich. Die Gesamtfläche zwischen 200cm2 und 230cm2 ist besonders vorteilhaft, wenn die elektrische Einheit eine Batterieeinheit eines Schienenfahrzeugs ist.In a preferred embodiment of the invention, a total area of the first openings and the second openings together is between 200 cm 2 and 230 cm 2 including a tolerance range. The limitation of the total area is required because of the requirements for ventilation and fire protection. The total area between 200 cm 2 and 230 cm 2 is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
Insbesondere können die ersten Öffnungen und/oder die zweiten Öffnungen jeweils gleiche oder jeweils unterschiedliche Durchmesser aufweisen. Dadurch können z.B. in Bereichen einer erhöhten Brandgefahr an der elektrischen Einheit kleinere Durchmesser gewählt werden als in weniger gefährdeten Bereichen.In particular, the first openings and / or the second openings may each have the same or different diameters. This allows eg in areas an increased fire hazard at the electrical unit smaller diameter can be chosen than in less vulnerable areas.
Bevorzugt weisen die ersten Öffnungen und die zweiten Öffnungen jeweils einen Durchmesser auf, der weniger als 25 mm beträgt, wobei der Durchmesser insbesondere 20 mm einschließlich eines Toleranzbereichs beträgt. Derart gewählte Durchmesser sind besonders vorteilhaft, wenn die elektrische Einheit eine Batterieeinheit eines Schienenfahrzeugs ist.Preferably, the first openings and the second openings each have a diameter which is less than 25 mm, the diameter being in particular 20 mm including a tolerance range. Such selected diameter are particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
In einer zweckmäßigen Weiterbildung der Erfindung sind zwischen den ersten Öffnungen und den zweiten Öffnungen Versatzabstände in einer Längsrichtung und/oder einer Querrichtung vorhanden. Dadurch kann eine Richtung einer Gasausströmung beeinflusst werden.In an expedient development of the invention, offset distances in a longitudinal direction and / or a transverse direction are present between the first openings and the second openings. Thereby, a direction of a gas outflow can be influenced.
Weiterhin können die Versatzabstände zwischen den ersten Öffnungen und den zweiten Öffnungen jeweils gleich groß oder jeweils unterschiedlich groß sein. Bei gleich großen Versatzabständen ist eine gleichmäßige Belüftung gewährleistet. Bei unterschiedlich großen Versatzabständen kann z.B. in stärker brandgefährdeten Bereichen an der elektrischen Einheit ein größerer Versatzabstand vorgesehen sein als in weniger brandgefährdeten Bereichen.Furthermore, the offset distances between the first openings and the second openings can each be the same size or different sizes. Equal ventilation distances are guaranteed for equal offset distances. For differently sized offset distances, e.g. In more fire-prone areas on the electrical unit be provided a greater offset distance than in less fire-prone areas.
Insbesondere sind die Versatzabstände zwischen den ersten Öffnungen und den zweiten Öffnungen jeweils größer als 25 mm. Hierbei wird ein Prüfkriterium für die Belüftung und den Brandschutz bei einer Batterieeinheit eines Schienenfahrzeugs erfüllt, d.h. eine Spaltlehre mit einem Außendurchmesser von 25 mm passt weder senkrecht noch schräg durch die versetzt zu einander angeordneten ersten Öffnungen und zweiten Öffnungen. Die Spaltlehre ist ein zylindrischer Stahlstab, der brandschutztechnischen Normen entspricht, und zu einer Überprüfung einer Einhaltung der Normen dient.In particular, the offset distances between the first openings and the second openings are each greater than 25 mm. Here, a test criterion for the ventilation and the fire protection in a battery unit of a rail vehicle is met, i. E. a gap gauge with an outer diameter of 25 mm fits neither vertically nor obliquely through the offset to each other first openings and second openings. The gap gauge is a cylindrical steel rod that complies with fire safety standards and serves to verify compliance with the standards.
Außerdem können zwischen den ersten Öffnungen und Rändern der ersten Deckplatte sowie zwischen den zweiten Öffnungen und Rändern der zweiten Deckplatte jeweils Randabstände vorhanden sein, wobei jeder Randabstand größer ist als ein jeweils vorgegebener Mindestabstand. Dadurch werden mechanische Anforderungen, d.h. Anforderungen an eine statische und dynamische Strukturfestigkeit, sowie fertigungstechnische Anforderungen erfüllt.In addition, between the first openings and edges of the first cover plate and between the second openings and edges of the second cover plate each edge distances may be present, each edge distance is greater than a respective predetermined minimum distance. As a result, mechanical requirements, ie requirements for a static and dynamic structural strength, as well as manufacturing requirements are met.
Speziell kann die erste Deckplatte und die zweite Deckplatte jeweils ein Material mit einem vorgegebenen Feuerwiderstand aufweisen, insbesondere mit einem Feuerwiderstand von 10 Minuten, wobei das Material insbesondere Stahl umfasst. Der vorgegebene Feuerwiderstand ergibt sich aus den brandschutztechnischen Anforderungen. Ein Feuerwiderstand von 10 Minuten ist besonders vorteilhaft, wenn die elektrische Einheit eine Batterieeinheit eines Schienenfahrzeugs ist. Stahl bietet im Allgemeinen einen guten Feuerwiderstand.Specifically, the first cover plate and the second cover plate may each comprise a material with a predetermined fire resistance, in particular with a fire resistance of 10 minutes, the material comprising in particular steel. The specified fire resistance results from the fire protection requirements. A fire resistance of 10 minutes is particularly advantageous when the electrical unit is a battery unit of a rail vehicle. Steel generally provides good fire resistance.
Vorzugsweise betragen eine erste Dicke der ersten Deckplatte und eine zweite Dicke der zweiten Deckplatte jeweils mindestens 1 mm einschließlich eines Toleranzbereichs. Eine derart bemessene erste Dicke bzw. zweite Dicke ist besonders vorteilhaft, wenn die elektrische Einheit eine Batterieeinheit eines Schienenfahrzeugs ist.Preferably, a first thickness of the first cover plate and a second thickness of the second cover plate are each at least 1 mm including a tolerance range. Such a dimensioned first thickness or second thickness is particularly advantageous when the electrical unit is a battery unit of a rail vehicle.
In einer vorteilhaften Weiterbildung der Erfindung ist die elektrische Einheit eine Batterieeinheit und/oder die erste Deckplatte und die zweite Deckplatte sind an einander befestigt, insbesondere mittels Nietverbindungen, und/oder die Abdeckungsvorrichtung ist an der Aufnahmevorrichtung befestigt, insbesondere mittels Schraubenverbindungen. Ein derartiger Aufbau ermöglicht eine einfache Montage bzw. Demontage. Wenn die Aufnahmevorrichtung für eine Batterieeinheit eines Schienenfahrzeugs vorgesehen ist, ist dieser Aufbau besonders vorteilhaft.In an advantageous development of the invention, the electrical unit is a battery unit and / or the first cover plate and the second cover plate are fastened to one another, in particular by means of rivet connections, and / or the cover device is fastened to the receptacle, in particular by means of screw connections. Such a structure allows easy assembly and disassembly. If the receiving device is provided for a battery unit of a rail vehicle, this structure is particularly advantageous.
Weiterhin besteht die Lösung der Aufgabe in einem Verfahren zum Schützen mindestens einer Umgebung mindestens einer Gehäuseanordnung. Bei einer Flammenentwicklung an der elektrischen Einheit bilden die erste Deckplatte und die zweite Deckplatte gemeinsam eine gasdurchlässige Flammensperre, wobei die erste Deckplatte und die zweite Deckplatte bei einer Flammenentwicklung an der elektrischen Einheit jeweils eine gleiche gasdurchlässige Position einnehmen wie bei einem flammenfreien Betrieb der elektrischen Einheit. Eine Gasdurchlässigkeit ist also sowohl bei einer Flammenbildung als auch bei einem flammenfreien Betrieb gewährleistet. Bei dem erfindungsgemäßen Verfahren werden somit vorteilhaft die Anforderungen an die Belüftung und den Brandschutz erfüllt. Dadurch ist ein sicherer Betrieb möglich, denn es kann auf einen störungsanfälligen Verstellmechanismus verzichtet werden.Furthermore, the solution of the problem in a method for protecting at least one environment of at least one housing assembly. In a flame development on the electrical unit, the first cover plate and the second cover plate together form a gas-permeable flame arrester, the first cover plate and the second cover plate occupy the same gas-permeable position with a flame development on the electrical unit as in a flame-free operation of the electrical unit. A gas permeability is thus ensured both with a flame formation and with a flame-free operation. In the method according to the invention thus advantageously meets the requirements for ventilation and fire protection. As a result, safe operation is possible, because it can be dispensed with a failure-prone adjustment mechanism.
Vorzugsweise kann bei einer Gasentwicklung an der elektrischen Einheit unabhängig von einem Auftreten von Flammen eine Gasströmung durch die zweiten Öffnungen, den Spalt zwischen der zweiten Deckplatte und der ersten Deckplatte und durch die ersten Öffnungen ausströmen. Auf diese Weise werden die Belüftungsanforderungen erfüllt, wobei die Gasströmung durch einen einfach aufgebauten Strömungsweg ausströmen kann.Preferably, gas evolution on the electrical unit, irrespective of the occurrence of flames, may cause gas flow through the second openings, the gap between the second cover plate and the first cover plate, and through the first openings. In this way, the ventilation requirements are met, whereby the gas flow can flow through a simply constructed flow path.
Beansprucht wird weiterhin ein Schienenfahrzeug mit mindestens einer Gehäuseanordnung.Claimed is still a rail vehicle with at least one housing assembly.

Im Betrieb können verschiedene Zustände der Batterieeinheit des Schienenfahrzeugs auftreten. Bei einem Ladevorgang der Batterieeinheit können Gase entstehen. Wenn die Batterieeinheit eine Blei- bzw. NiCad-Batterieeinheit ist, können bei einer Überhitzung Rauchgase ohne eine Flammenbildung entstehen. Wenn die Batterieeinheit eine Lithium-lonen-Batterieeinheit ist, kann bei einer Überhitzung eine Flammenbildung auftreten. Die Erfindung und das Ausführungsbeispiel beziehen sich in erster Linie auf Lithium-lonen-Batterieeinheiten, können aber auch bei Blei- bzw. NiCad-Batterieeinheiten eingesetzt werden. Somit kann die Gehäuseanordnung 10 bei einem Wechsel eines Typs einer Batterieeinheit beibehalten werden.During operation, various states of the battery unit of the rail vehicle may occur. When charging the battery unit, gases may be generated. If the battery pack is a lead or NiCad battery pack, overheating can produce fumes without flaming. If the battery pack is a lithium-ion battery pack, overheating may cause flame formation. The invention and the embodiment relate primarily to lithium-ion battery units, but can also be used in lead or NiCad battery units. Thus, the
Bei dem Ladevorgang können die Gase durch die zweiten Öffnungen 31, den Spalt 40 und die ersten Öffnungen 21 ausströmen. Auch Rauchgase können durch die zweiten Öffnungen 31, den Spalt 40 und die ersten Öffnungen 21 ausströmen. Bei einem Auftreten von Flammen an der Batterieeinheit werden diese mittels der Abdeckungsvorrichtung 12 an einem Austritt aus der Gehäuseanordnung 10 gehindert. Die Abdeckungsvorrichtung 12 besitzt dabei eine Prallwirkung, d.h. die Flammen prallen an der Abdeckungsvorrichtung 12 ab. Die Prallwirkung wird dadurch erzielt, dass die Flammen zunächst zwischen den zweiten Öffnungen 31 auf die zweite Deckplatte 30 prallen. Ein Teil der Flammen tritt durch die zweiten Öffnungen 31 hindurch und prallt zwischen den ersten Öffnungen 21 auf die erste Deckplatte 20. Die zweite Deckplatte 30 und die erste Deckplatte 20 bilden also gemeinsam eine Flammensperre.During the charging process, the gases can flow out through the
Eine Blei- bzw. NiCad-Batterieeinheit kühlt von selbst ab, und eine Rauchbildung verringert sich, wenn eine Initialenergie, d.h. eine die Überhitzung auslösende Energie, entfernt wird. Bei einer Lithium-lonen-Batterieeinheit können die Flammen nicht aktiv gelöscht werden. Wenn das gesamte Lithium oxidiert ist, verlöschen die Flammen von selbst. Die dabei entstehenden Gase können durch die Abdeckungsvorrichtung 12 ausströmen und damit ein schnelleres Verlöschen der Flammen bewirken. Sowohl bei einer Blei- bzw. NiCad-Batterieeinheit als auch bei einer Lithium-lonen-Batterieeinheit sorgt das Ausströmen von Gas für ein besseres Abkühlen der Batterieeinheit nach einem Ende der Überhitzung bzw. Flammenbildung.A lead or NiCad battery pack cools by itself, and smoke builds up when initial energy, i. an overheating energy is removed. With a lithium-ion battery unit, the flames can not be actively extinguished. When all of the lithium is oxidized, the flames go out by themselves. The resulting gases can flow out through the
Alternativ zu der Batterieeinheit des Schienenfahrzeugs können auch andere Arten von überhitzungsgefährdeten elektrischen Einheiten verwendet werden.As an alternative to the battery unit of the rail vehicle, other types of overheating-prone electrical units may be used.
